[gcc]
2015-01-06 Bill Schmidt <wschmidt@linux.vnet.ibm.com>
* config/rs6000/vsx.md (*p9_vecload_<mode>): Replace VSX_M
mode iterator with VSX_M2.
(*p9_vecstore_<mode>): Likewise.
(*vsx_le_permute_<mode>): Restrict to !TARGET_P9_VECTOR.
(*vsx_le_perm_load_<mode> for VSX_LE_128): Likewise.
(*vsx_le_perm_store_<mode> for VSX_LE_128): Likewise.
(define_split for VSX_LE128 stores): Likewise.
(define_peephole2 for TImode LE swaps): Likewise.
(define_split for VSX_LE128 post-reload stores): Likewise.
